Ingredients editor not appearing in datatype list

[FootswordTechnologies]

Hi,

I think there is a step missing in the Angular workbook. I have completed the third exercise and am now stuck. I have the package manifest for glasses in the "first" folder and all the other glass files in "glass" folder. These work very well. I created a new folder, called "ingredient" and four new files, including a new package manifest. The trouble is, the new "ingredient editor" just isn't appearing in the datatype dropdown, so I can't select it. I can't help feeling this is somethign to do with the package manifest. Surely I only need one? I include my app_plugins folder.

Never mind. I still have no idea what went wrong but I copied the files from the help and it worked. Strange. I had read every comma (I thought).
